Question

Hedi adds 5 to a number, then multiples the sum by negative 2. The
result is 6. What is the number? *

Answer 1

Answer:

$x=-8$

Step-by-step explanation:

Let's say that the number is x. Hedi adds 5 to the number, then multiplies its sum by -2. The result is 6. Writing this out as an equation:

$-2(x+5)=6$

So now we solve for x. First, we divide both sides by -2, giving us:

$x+5 = -3$

Then, to finish the problem, we subtract 5 from both sides:

$x=-8$

Thus, the number Hedi started with was -8

Hope this helps!
